World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

Nuclear clocks should be more robust and portable than the best available clocks today because nuclei are hard to perturb and ...

The alternative text for this image may have been generated using AI. The DSAC ion clock, payload configuration and ground testing, as well as its navigational uses and some scientific applications, ...

As applications of frequency combs have expanded, their uses have extended beyond functioning simply as a reference ruler 3,4,5. For example, many experiments combine two or more frequency combs for ...

Researchers have shown, for the first time, that transmission of ultrastable optical signals from optical clocks across tens of kilometers of deployed multicore fiber is compatible with simultaneous ...

An atomic clock research team from the National Time Service Center of the Chinese Academy of Sciences has proposed and implemented a compact optical clock based on quantum interference enhanced ...

Clocks are the heartbeats of embedded systems, providing timing references and synchronization between components, subsystems, and entire systems. Incorrect clock signal amplitudes and timing can ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

A recent blog post discussed the challenges of clock signal integrity and clock jitter in deep submicron semiconductor devices. Nice, clean clock signals are degraded due to many factors, including ...

RF absorption and PLL phase calibration help phased-array subsystems reduce clock spurs while preserving spectral purity and ...

At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it’s fraught with the most problems at the ...
